| Abstract Scope |
The mucus lining of the respiratory system protects the lungs from environmental factors. This viscoelastic biological hydrogel also interacts with drug-containing liquid plugs. Yet how mucus affects the transport and delivery of liquid plugs remains unknown.
What is well established is the deformation of a soft viscoelastic gel near a contact line, resulting in a wetting ridge around a static drop. The wetting ridge is associated with viscous dissipation in the gel when the drop moves. To study the influence of a mucus-like lining on the imbibition of a partially wetting fluid, we produce capillary tubes coated with a soft silicone gel. We characterize the imbibition rate for different tube diameters, gel thicknesses, and fluid properties. Our results indicate two imbibition regimes: at low gel thickness, dissipation is negligible; at high gel thickness, gel deformation influences the motion of the contact line and the imbibition rate. |
